This invention relates to a flush tank valve for water closets and aims to provide a construction which does not depend upon the employment of a nozzle or jet but one which will work on the weakest of water systems and is particularly applicable for the up to date low down type of water closet.

A particular object is to provide a valve action which upon slight Operation will immediately permit a full head of supply water to enter the tank and continue wide open until the tank is emptied, thereby delivering more water to the water closet than existing constructions of the same dimensions and which even if the toilet should be flushed several times in quick succession or the lever be held down, will not in any way interfere with the flushing of the valve. In addition it is aimed to provide a construction which is noiseless and which will avoid trickling or dripping noises in particular and which are so common in present day appliances.

The more specific objects and advantages will become apparent from a consideration a of the description following taken in connection with accompanying drawings illustrating an operative embodiment.

In said drawings Figure 1 is a view in transverse section through a flush tank showing my improved valve mechanism in place,

Figure 2 is a plan view of the parts of Figure 1,

Figure 3 is an enlarged central vertical sectional view through the tank and valve mechanism,

Figure 4: is a cross sectional view on the line 4-4 of Figure 3, and

Figure 5 is a cross sectional View taken on the line 5-5 of Figure 1.

Referring specifically to the drawings, 10 designates a conventional flush tank adapted to contain water normally to the level indicated at A and which is siphoned out through the operation of the apparatus to the level indicated at B. The water supply tube com nected to the tank is shown at 11 and it is. preferably crooked as shown in the drawings so that the same may be attached to any and all types of modern water closet tanks.

Surmounting the supply tube 11 is a casing 12, the same being fitted tothe tube 11 by an adapter 13, preferably screw threaded both to the tube and to the casing. Such casing mounts a vertically movable cock 14: which coacts with a valve seat 15 within the casing 12 to control the supply of Water. i

A. discharge pipe or tube 16 l'eads from the valve casing and communicateswith the in teriorof the tank while a refil'l pipe ortube 17 also leads from the valve casing 12''. The pipe 17 discharges into a flush pipe section 18 suitably connected to the tank and connected to a flushpipe19 leading to the water closet bowl suchfiush pipe having a goose neck or trap QOtherein.

The flush pipe section 18- is surmounted by a siphon shell 21 which has ablock: 22 in the top thereof adapted to rest on the adjacent portion of pipe 17 to maintain the shell spaced from the inlet of pipe 18 In addition, spacingvanes 23 on the, pipe 18 maintain the siphon shell in proper spaced relation. The shellis open at the bottom, terminating at the line B.

It will be noted that a vent hole is provided at 24' through the wall of shell 21 for in stance one-thirty-second of} an inch in diameter. This vent hole serves to slow down the siphon action and prevent-occurrence of a-continuous siphon where there is too large a volume of Water entering the tank through thevalve.

Attention is called to the fact that the bore of pipe 16' isless than that of the seat 15 and.

accordingly sufficient Water. enters the supply pipe .11 to be diverted into streams through both the pipes 16 and 1'7. The refill water passing through pipe 17 acts as a timer for the bowl and siphon tube.

PATENT OFFICE A lever is pivoted at 26 to an arm on the casing 12 and at a projection 27 bears downwardly on the valve or cook 14. The other end of the lever 25 is pivoted at 28 to a link 29 in turn pivoted at 30 to a trigger plate 31. A T-shaped bracket 32 is pivoted at 33 to the plate 31 and at 34: to an arm 35 of the valve casing 12. From the bracket 32 a rod 35 extends which carries the float ball 36. A weight or pendulum 37 may be suspended from the plate 31 so as to urge the same to normal position. The device is adapted to be actuated through pulling movement exerted on a rod 38 pivoted to the plate 31.

It will be noted that normally or when the tank is full of water, the pivots 28, 30 and 33 are substantially in vertical alinement as shown in Figure 1 and that the link 28 bears against a lug 39 formed on the plate 31 and best shown in Figure 5, limiting the movement of the parts to such position upon the refilling of the tank.

The upper water level is at substantially the top of the flush pipe section 18 at which level there is very low air pressure sealed i11- side of such tube. Thus when the trigger plate 31 is moved from the position of Figure 1 slightly to the right as shown in full lines in Figure 3, water will fill the tank and the water level is raised over and above the shell 21 which creates greater air pressure inside the pipe or tube 18. WVhen the water level has reached the height of approximately two inches above the top of said shell, a sufficientair pressure is created to force the air out through the flush pipe or lower siphon 19 and immediately the siphonic action starts, slow at first but increasing in speed until the air intake through the vent 2 1 slows it down progressively until the bottom of the shell 21 or lower water level is reached.

Various changes may be resorted to provided they fall within the spirit and scope of the invention.

I claim as my invention 1. In a device of the class described, a valve to control a water supply pipe, a lever engaging the valve, a link pivoted to the lever, a trigger plate to which thelink is pivoted, a float valve means pivoted to the trigger plate and to the support for said lever, and a stop means limiting the relative movement of said link and trigger plate.

2. In a device of the class described, a valve to control a water supply pipe, a lever engaging the valve, a link pivoted to the lever, a trigger plate to which the link is pivoted, a float valve means pivoted to the trigger plate and to the support for said lever, a stop means limiting the relative movement of said link and trigger plate wherein the pivots of the link and of the fioat valve connection to the trigger are in substantial vertical alinement.

3. In a device of the class described, a valve to control a water supply pipe, a casing for said valve, a lever engaging the valve, a link pivoted to the lever, a trigger plate to which the link is pivoted, a float valve means pivoted to the trigger plate, means pivoting said float valve means and said lever to said casing on opposite sides of the valve, a stop means limiting the relative movement of said link and trigger plate.

In testimony whereof I affix my signature.
